After the 14.18 updates recently, the link for Trueplay was sent to me in my iPad and I duly did it in my room which consisted of the Arc, a pair of One SLs and the Sub Mini. There was no problem (both steps) and i was successful on the first occasion and of course the overall sound improvement was instantly noticeable.
Unfortunately I cannot say the same for my set up in the hall. I have my Playbar, Sub Gen 3 and a pair of One SLs. I was unable to even get through the first step of the Trueplay because apparently there is some noise interference in the hall. I had this done at 5am in the morning with everything off except the lights and no outside noise either. I have been trying since but have been unsuccessful all the time - not even the first step. For your information the set up was on Trueplay before the updates. Can anyone enlighten me on what to do about this?
